Some have thought that the apsidal Lady Chapel of Lichfield Cathedral built about fifty years earlier suggested an apsidal termination in the design of Coventry, but a certain difficulty in the way of the designer may have led him to adopt this solution. The normal Perpendicular east end had one large window, but owing to the great width of this chancel the proportions of such a one would have been nearly square, and the spring of the arch have been very low. A few years later and the depressed four-centred arch might have been adopted but, fortunately, its time was not yet. The plans of the apses of Lichfield and Coventry differ in the angle at which the sides are inclined to the chord of the apse, the former having the usual angle of 45°, the latter one of more than 60°. Externally this is not so pleasant as the more "commonplace" form, the great dissimilarity of the several angles being unsatisfactory and the third side too quickly lost to view, but within the church these points are not noticed. So little time elapsed between the building of the choir and nave that we find no marked difference of style as we proceed westward along either flank of the church. The =Lady Chapel=, known as the Drapers' Chapel, from its use and maintenance by that Gild, occupies the three bays of the North chancel aisle. From its elevation above the ground it was often spoken of as the "Chapel on the Mount," Capella Beatæ Mariæ de Monte. All the four windows are of seven lights, the three northern having a somewhat unusual transom band of fourteen quatrefoils, at the spring of the arch. The two windows of St. Lawrence's Chapel have a transom across the lights and a band of seven quatrefoils at the spring.
